0xc00007b Error when trying to login in from Launcher

I cannot find a fix for this, googling it says this is the error you get when a 32 bit app tries to run as a 64 bit app.

I did a clean windows install bc I was having issues with this and other games. I seem to have resolved the other errors, but ive had this game installed on 3 different computers over the years including this one and Ive never seen this error.

I tried searching for the error using the forum search and got no results.

The only other issue im having right now is is I cannot reinstall directX, i get an error for that as well.

Ive run every bit of trouble shooting I can find and nothing is fixing this or the direct X problem which I only started investigating bc googling issues with RoR led me to believe it was a direct X issue.

Not sure if its related or matters, but this is the error log from direct x:

[11/23/25 23:20:21] module: dsetup32(Mar 30 2011), file: dxupdate.cpp, line: 280, function: CSetup::InstallPlugIn

DirectXUpdateInstallPlugIn() failed.

grab a copy of 32bit d3dx9_34.dll and drop it into game folder and try again
your OS has issues with directx9c installation probably

I did that, and ran every other trouble shooting from the forum. Its reverted back to the launcher wont even open when I click the icon even if I try to run as admin.

I dont know why this started, or how it persisted through a clean windows install but sadly I think I cant play this.

one more thing you can try. try with DXVK ..aka translating dx9 to vulkan.
grab:
https://github.com/doitsujin/dxvk/releases

the tar.gz and extract it. drop the 32bit d3d9.dll into the RoR folder and give it a spin
